  • Background: The multidrug resistance 1 gene (MDR1) C3435T polymorphism has been demonstrated to influence the P-glycoprotein (P-gp) activity level which is related to inflammation and carcinogenesis. This meta-analysis was performed to estimate the association between the MDR1 C3435T polymorphism and the risk of gastric cancer (GC) and peptic ulcer (PU). Materials and Methods: A literature search was conducted with PubMed, Embase and the Cochrane library up to November 2013. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of association. Data were analyzed using Review Manager (Version 5.2), and Stata package (version 12.0) for estimation of publication bias. Results: Six case-control studies were included, of which five were for GC and two for PU. Overall, no evidence was found for any association between the MDR1 C3435T polymorphism and the susceptibility to GC and PU. In the stratified analysis by H. pylori infection status, stage and histology classification of GC, and PU type, there was still no significant association between them. Conclusions: This meta-analysis suggested that the MDR1 C3435T polymorphism is not associated with susceptibility to GC and PU. Large and well-designed studies are warranted to validate our findings.

  • Squamous cell carcinoma (SCC) of the retromolar trigone (RMT) is a rare but potentially fatal disease that carries a poor prognosis due to its unique anatomic position. RMT SCCs tend to spread to vital nearby structures, including the tonsillar pillar, masticatory muscles, and underlying mandibular bone, even in their early stages, and aggressive treatment is often warranted. This systematic review appraises and qualitatively analyzes all available literature regarding the survival outcomes and prognosis of RMT SCC. Four databases were searched to identify all eligible articles published since January 1980. Of the 1,248 studies, a total of 15 studies representing 4,838 cases met the inclusion criteria. The evaluated patients had a high rate of advanced tumor stage (T3 or T4: 61.4%), lymph node metastasis (38.8%), and mandibular bone invasion (24%) at the time of diagnosis. Aggressive surgical treatments such as lip-splitting (92%), segmental mandibulectomy (61.1%), radical neck dissection (44.1%), and reconstruction using free flaps (49.5%) was undertaken for 92% of the pooled patient population. The mean rates for local, regional, and systemic recurrence were 23.40%, 8.40%, and 8.50%, respectively. The mean 5-year overall survival rate was 38.90%. Osteonecrosis was noted in 11.6% of the 328 patients who received radiotherapy. In conclusion, RMT SCC is generally associated with high recurrence, low survival, and high postoperative complication rates. Early diagnosis and aggressive treatment are thus warranted. However, significant methodological problems hamper current knowledge. Future studies of this topic that use randomized or cohort designs are thus needed.

  • 현대 의학의 눈부신 발전에도 불구하고 감염병의 유행 발생과 전파는 지속적으로 인류를 위협하고 있으며, 이러한 감염병의 사람 간 전파는 사회적 접촉에 의한다. 그러나 사회적 접촉에 관한 국내 연구는 초기 단계다. 본 연구에서는 체계적 문헌 고찰을 통해서 각국의 사회적 접촉의 실태를 파악하여 국내 연구를 위한 기초자료를 제공하고자 한다. 문헌 선정기준은 2000년 이후부터 2017년 12월까지 영어로 발표된 전국적인 규모의 사회적 접촉 논문 12편을 최종선정하였다. 후향적 접촉일지(7건, 58.3%), 무작위 추출법(9건, 75%)을 연구방법으로 가장 많이 이용하고 있었으며, 접촉자 수는 4.9명-17.7명/일, 주중에 주말보다 더 많았으며, 매일 만나는 관계에 있는 사람과 주로 접촉하였고, 신체적 접촉은 가정 내에서 빈번하였다. 접촉 빈도가 가장 높은 연령은 5-19세로 감염병 유행 발생 시에는 이 연령층에 의한 감염전파가 우려된다고 볼 수 있다. 특히 동질성혼합(assortative mixing)은 5-20세 군에서 높아 이 연령층은 동일한 연령대와의 접촉으로 인한 감염전파 가능성이 큼을 시사하므로 이 연령층에 대한 감염 예방대책이 필요함을 보여주고 있었다. 그러므로 국내에서도 새로운 감염병 또는 재유행 감염병의 발생이나 관리의 정확한 예측을 위해서 국내 기반의 사회적 접촉양상을 파악하여, 이를 기초로 국내 감염병 유행 발생의 예측과 감염 예방대책 수립이 이루어져야 할 것이다.

  • Objectives: To review studies evaluating effects of acupuncture on pain and depressive symptoms in fibromyalgia. Methods: Quantitative evidences (RCTs) were systematically reviewed. Literature were searched for a combination of fibromyalgia and depression (The Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, medline (via PubMed), Kmbase, KISS, ScienceON, OASIS, CiNii, CNKI). Quantitative research findings were critically appraised by Cochrane risk of bias (RoB) tool and pooled. Meta-analysis was then conducted using Review Manager (RevMan) 5.4. Results: Eighteen studies were selected. American College of Rheumatology (ACR) classification criteria for Fibromyalgia Syndrome was most frequently used as diagnostic criteria for fibromyalgia. As for outcome measurement, Hamilton Rating Scale for Depression (HAMD), Visual Analog Scale (VAS), and Total Effective Rate (TER) were used most commonly. Meta-analysis of ten studies revealed that both Depression and VAS scores of the Acupuncture+Western Medicine group were significantly lower than those of Western Medicine group (Depression: SMD, -0.94, 95% CI, -1.17 to -0.70; VAS: MD, -1.51, 95% CI, -1.83 to -1.19). Also, TERs of both Acupuncture group and Acupuncture+Western Acupuncture+Western Medicine group were significantly higher than those of the Western Medicine group (OR: 2.38, 95% CI: 1.29 to 4.41; and OR: 7.40, 95% CI: 3.41 to 16.07). There was no significant difference in Depression or VAS score between the Acupuncture Group and the Western Medicine Group. Conclusions: Acupuncture might be an effective option for pain and depressive symptoms of fibromyalgia when it is combined with Western Medicine treatment. For more accurate results, more types of Korean medicine treatment should be conducted.

  • Objectives : Depression disturbs the individual life from the loss of productivity to suicide. Furthermore the whole society is also influenced by depression in social and economic areas. Many scientific treatment methods are known to be effective in depression. But in reality more than half of patients with depression prefer self help treatment rather than medically based treatment. For the patients with mild depression and primary physicians, it is reasonable to provide the evidence based self care including self help or alternative treatment. This study is supported by the Korean Health 21 R&D Project for the Depression Center to establish the Korean treatment guideline for depression. Methods : The members of Depression Center including the authors attended the workshops where the methods of evidence based medicine such as literature search, quality evaluation of the articles, making the level of evidence were educated. The professional librarians helped the authors for get the searched articles. Among the total of 354 abstracts of systemic review and 300 abstracts of random controlled trials, 3 systemic reviews and 2 random controlled trials were the main structure of evaluation. Result : Among the 37 self care methods known to be effective for depression, 11 kinds of methods were worth of evaluation. The first step for the self care of mild depression is to use St. John's wort, exercise, bibliotherapy, and light therapy in depression during winter season. Acupuncture, negative ion therapy, massage, relaxation technique are known to be efective with evidence. Music therapy, hypnotherapy, and aromatherapy are known to be effective but until now the evidences is insufficient and further evaluations are needed. Conclusion : Among 11 listed self-care methods, several methods need more evidence especially in Korean situation. Exercise is the most recommendable evidence based self care method in Korea nowadays. St. John's wort is effective with evidence, but it is not the OTC drug in Korea, so it is not recommendable now. For the bibliotherapy, there is no book such as "Feeling Good" in Korea. Only the introductory book about depression is available. Publishing the self help book based upon cognitive behavioral approach or psychodynamic approach is needed. Light therapy is practiced in a few clinics, but not self-help style. Exposure to the sunlight is recommended in the level of commen sense. These self care methods are for the mild patient. Moderate to severe patients with depression should seek the professional treatment.

  • CyberKnife is a stereotactic radiosurgery system which could be used to treat many tumors and lesions. It provides the surgeon unparalleled flexibility in targeting using a compact light linear accelerator mounted on a robotic arm. Advanced image guidance technology tracks patient and target position during treatment, ensuring accuracy without the use of an invasive head frame. CyberKnife with Dynamic Tracking Software is cleared to provide radiosurgery for lesions anywhere in the body when radiation treatment is indicated. It has often been used to radiosurgically treat otherwise untreatable tumors and malformations. Moreover, this instrument treats tumors at body sites, most of which are unreachable by other stereotactic systems. Compared with conventional radiotherapy, it is fundamentally different that using non-invasive, frameless, no excessive radiation exposure to normal tissue. In oral malignant neoplasm, surgical excision and radiation therapy should be tried first, additionally chemotherapy could be considered. However, after failure of conventional therapies, patients had poor systemic condition and surgical limitation. So, CyberKnife could be a suitable therapy. A 49 years man was referred in recurred mandibular cancer treated by radiotherapy. The tumor was considered inoperable, because of extensive invasion and was not expected to good response to conventional therapies. We experienced a case of CyberKnife after 4 cycle chemotherapies, so we report it with review of literature.
